This work details the scalable and solventless synthesis of a potential fully biobased monobenzoxazine resin derived from tyrosol and furfurylamine. The structure of the monomer was studied by nuclear magnetic resonance (NMR) spectroscopy and Fourier transform infrared (FTIR). The curing of the precursors was characterized by differential scanning calorimetry (DSC), rheological measurements, and thermogravimetric analysis (TGA). The properties of the resulting biobased polybenzoxazine were then determined by thermogravimetric analysis (TGA) and dynamic mechanical thermal analysis (DMA). A thermally stable resin was obtained with 5% and 10% weight-reduction-temperature ( and ) values of 349 and 395 °C, respectively, and a char yield of 53%. Moreover, the low melting temperature, low viscosity, and excellent thermomechanical behavior make this fully biobased resin a promising candidate for coating applications.
这项工作详细介绍了一种由酪醇和糠胺衍生而来的潜在全生物基单苯并恶嗪树脂的可扩展且无溶剂合成方法。通过核磁共振（NMR）光谱和傅里叶变换红外（FTIR）光谱研究了单体的结构。通过差示扫描量热法（DSC）、流变学测量和热重分析（TGA）对前体的固化过程进行了表征。然后通过热重分析（TGA）和动态热机械分析（DMA）确定了所得生物基聚苯并恶嗪的性能。获得了一种热稳定树脂，其5%和10%失重温度（ 和 ）值分别为349和395 °C，残炭率为53%。此外，低熔点温度、低粘度和优异的热机械性能使这种全生物基树脂成为涂料应用的有前途的候选材料。
